Medicament Delivery Device

A medicament delivery device comprising:

• a housing comprising a proximal end and a distal end;
• a needle and a needle cover,
• wherein the needle cover is axially movable between an extended position, in which the needle cover extends from the distal end of the housing and covers a distal end of the needle, and a retracted position, in which the needle cover is located in a proximal position relative to the extended position such that the needle protrudes from a distal end of the needle cover;
• and
• a needle cover biasing member configured to bias the needle cover axially in a distal direction towards the extended position, wherein the needle cover biasing member is located within the needle cover,
• wherein the needle cover biasing member is configured to transition from a non-buckled state to a buckled state during proximal movement of the needle cover from the extended position to the retracted position, wherein when the needle cover biasing member is compressed yet before the needle cover biasing member has transitioned from the non-buckled state into the buckled state, the needle cover biasing member is arranged substantially along an axis, wherein the axis is defined by a first end of the needle cover biasing member and a second end of the needle cover biasing member that is opposite to the first end, and the axis is parallel to and radially outward from a longitudinal axis of the needle.
